IMPROVEMENT m RULiNG-MACHIIIES.

Sfiecification forming part of Letters Patent N0. 148,381, dated March 10, 1874; application fi1ed February 7, 1874.

T0 all whom z't may concern:

Be it known that I, EDWIN J. PIPER, of Sp'ringfield, Hampden county, State of Massach'usetts, have invented certadn Improvements in Ruling-Machines, 0f which the following is a speoification:

My invention consists in the combination With the drum 01' pen-cylinder of a .rulingmchine, and with the peu-bar and stop-gate thereof, 0f a detaehed hub with adjustable c2uns, arranged up0n an axle from the frame, coincident with the axis 0f the pen-ylinder, and in which ehe shaft 0f the peu-cylinder finds a bearing, and so that 1:11e hub 02m1 be thrown in cluc'eh With the pen-cylinder to operate the peu-bar and stop-gate relatively thereto, orreleased wheh it is desired. 130 d0 'continuouS ruling, and 02m have its cams quickly and accurately adjusted. to varioussized drums that may be used in the rulingma0hine; the obje'ct: 0f the invention being t0 simplify theeonstruction 0f this cl ass 0f machinery, by enabling one set 0f cams, whi1e operating 100'011 the peu-bar and stop-gae, t0 be adapted to t-he various-sized cylinders required.

In the dmwings, Figure I is a plan view 0f a maehine having my improvements. Fig.ll is .L partial side section upon 1ine x x, Figs. III and IV beirig detail views.

B B is the frame, having the peu-bar D and stop-gate F W0rking in the usua-l manner in bearings therefrom, tlie stop gate containing the pins c 0 c, &e., whieh come against the apron and regulace the feed 0f stock. The

peneylinder H has one end. of its shafiq resting in the frame at h, while the other is received within the axle d, which proceeds from the frame. Loose upon the axle d is the hub G, which has a groove in one side, zus shown in Fig. II, to receive the end 0f shipper-handle V, and is also provided with deep recesses g g in its perimeter t0 contain the cam-sections b b b, &c.,- which recesses g g hawe screwholes communicating witl1 them fr0m the sides of the hub to admit the elamp-screws e e e, &c., intended to hold. can'1-sections b b b and cams ff, &c The handle V is slid upon the frame, when released by its thumbscrew k, to

m0ve the hab G upon ios axle, and the face 0f the hub toward the pen-eylinder is provid=-d with the pin y t0 engage with the 011111011. m upon the shaft 0f the pen-cylinder. The eams b b, &c. operate the peu-bar D, through the paw1 s, and the eams f f trip the stop-gate by means 0f the pawl t.

When it is desired t0 change the pen-cylinder in the machine, 130 either substitute a larger 01' smaller one, it is li fted out from its bearings in the frame and. ax1e d, and the cams b b b am]. ff are quickly adjusted by means of their clamp-screws e e e, &c., to the altered diameand feeding, while the machine, with a sei: 0f

difi'ereI1t-sized pen-eylinders, needs only the one set 0f c2uns.

I am mvare that machines having pen-cylinders, with the cam-heads fixed directly to each of their ende, have been used; also that the stop-gate shaft 11as been made t0 throw 2b pulley, containing cams 120 operate the penbar, into olutch With another pulley upon the pen-cylinder, t0 cause the two to intermittingly m0ve together, but disclaim all coutained in these 01' similzpr deviees; but

What I c1aim is The hub G, provided with adjustable cams b b b ff and pin y, in combination wioh clucch m 0f a pen-cylinder shaft, for operating both the peu-bar and stop-gate, substantially as described.

EDWIN J. PIPER.
